Sol Perimeter

The Sol Perimeter is an ultra massive, multi-layer defensive shield deployed between the orbit of Pluto and the former Kuiper Perimeter, and is one of two primary outer system defensive shields created to provide an extra layer of protection for Earth, acting as the first line of defense in the protection of Earth. It is joined in its work by the Earth, Jupiter, Mars and Pluto Perimeters. It is one of five replacements build by the Brayburn Society to replace the flawed and failed Oort and Kuiper Perimeters, and is built from their parts, gathered together as first the Oort, and later the Kuiper perimeters were deactivated, disassembled, and their parts then brought into the inner solar system to be redeployed as part of the new shield perimeters there.
